ROAD-BED FOR RAILROADS.

Application filed December 3, 1915.

To all whom it may concern:

l-le it known that I, AUGUST J. DINKLAGE,

a citizen of the United States, and resident of East Orange, county of Essex, State of New ersey have invented certain new and useful Improvements in Road-Beds for Rail roads, of which the following is a specification.

My invention relates to road-beds for railroads and more particularly to road-beds which are laid upon trestles, bridges or elevated structures. In such cases the ties are generally laid upon girders which when traflic passes over the rails, are subjected to a force tending to displace them upon said girders, this being particularly true if de vices for checking the creep of the rails are included in the structure. The particular object of my invention is to provide a simple and efifective means whereby this displacement of the ties is prevented and the latter are firmly and efficiently secured in their intended positions on the supporting girders. ll ly improvement will be fully described hereinafter and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings in which Figure 1 is a side elevation of a portion of a road-bed illustrating an example of my improvement in use; and Fig, 2 is a cross section thereof on the line 2-2 of Fig. 1.

'lhesc drawings show a specific means for ccmnplishing the objects I have in mind, it being understood that this is only an eX- ample used for the purpose of illustrating and describing my improvement and that the particular means shown may be replaced by other types adapted to bring about the same results.

is shown in the drawings the road-bed includes supporting girders 5 which may form part of a trestle, bridge or elevated structure or which. may in some cases rest upon the, ground and in all cases extend in parallel pairs in the general direction of the railroad. Upon these girders 5 the ties '6 are laid at spaced intervals and transversely thereto in the customary manner, the said ties 6 in turn supporting the rails 7 which may be secured thereto in any usual way as by means of spikes or the like 8.

As shown 'in the drawings the road-bed further includes devices for checking the creeping tendency of the rails occasioned by the traliic over the road-bed, which dev1ces Specification of Letters Patent.

Patented July 3, 1917., Serial No. 64,804.

for illustrative purposes and by way of example have been shown in the form included in applicants United States Patent .No. 1 ,015,? 91 of January 80, 1912. These devices comprise a shoe or clamp 9 adapted to fit over the rail base 7 and having curved ends 10 which bear upon said rail base as clearly shown in Fig. 2. A wedge 11 extends between the said shoe or clamp 9 and the lower surface of the rail. base 7 and is provided with a wedging surface 12 arranged to bear upon a portion of the said shoe or clamp 9. The said wedge 11 may further include a head 13 located in engagement with one of the ties 6, it being understood that the wedge 10 points in a general direction opposite to that in which the rail tends to creep. Thus as the said rail 7, under the forces exerted by the traflic thereover tends to move in the direction of its length relatively to the tie, the shoe or clamp 9 will be carried along toward tie tie 6. As the latter engages the head 13 the said tie will resist any tendency of the wedge 11 to move along with the shoe or clamp and will thus cause said clamp to be forced farther upon the wedge 11 and its wedging surface 12. As this happens the wedging surface 11 will force the ends 10 of the clamp or shoe 9 into firm and gripping engagement with the rail base 7 and will in consequence firmly and securely clamp the rail in position and arrest its tendency to creep. This arrangement how ever necessitates a tie 6 which presents a sub stantially immovable obstruction against which the wedge 11 or more specifically its head 13 is arranged to bear it being apparcut that the forces exerted by the anti-creeping device have a tendency to displace the tie or to slue it around as it were. In order to prevent this, in all cases where the ties are laid on girders or the like 5, I provide a device having the same general characteristics as the anti-creeping device and comprising a shoe or clamp 9" adapted to fit over a flange 5 of the girder 5 and having its ends 10 bearing upon the lower surface of said flange as clearly shown in Fig. 2. In this case a wedge 11 extends between the clamp or shoe 9 and the upper surface of the flange 5 and is formed with a wedging surface 12 arranged to engage the clamp 9 and may also have head 13 located in engagement with the tie 6. It will be seen by reference to the drawings that the clamps 9 and 9 are located at opposite sides of the tie 6 and that the heads 18 and 13 engage opposite surfaces thereof so that the wedge 11 pro- :IBCCS in a direction opposite to that in which the wedge 11 extends or in other words projects in the direction in which the tendency to displace the tie is exerted. In other words the two devices, comprising in the present instance the clamps and wedges are arranged to work in opposition to each other.

Thus as the anticreeping device tends to force the tie 6 out of place, any movement of said tie will cause the wedge 11 to be moved relatively to the shoe or clamp 9 which is held against movement by the frictional contact of its ends 10" with the flange 5,. This relative movement of the wedge 11- will cause the wedging surface 12 to bring said ends 1O" into still firmer engagement with said flange 5 whereby any further movement of said wedge is arrested with the result that the displacement of the tie 6 will be checked almost immediately and certainly before the same has assumed any dangerous proportions. The greater the tendency of the rail to creep the more firmly will the anti-creeping device be clamped to the rail base 7 while the greater the force exerted by the anti-creeping device against the tie 6 in the operation of checking this creeping tendency the more firmly will the shoe 9 be clamped to the flange 5 and the more etfi: ciently will the Wedge 11 arrest the shoving or displacing of the said tie. The latter is thus firmly secured in position at all times and under all conditions and the danger of the exerted forces being sullieient to dislocate the tie or to fracture the retaining devices as is the case with existing arrangements is entirely obviated. The device for checking the creep of the rail and the device for arresting the displacement of the tie when in the form shown may be placed in position in substantially the same manner as described in the patent hereinbefore referred to; In any case the devices of whatever form they may be are easily and operatively combined with the road-bed and provide an efficient means whereby the rails and the ties are firmly secured in position. In some cases the clamp 9 and wedge 11 with their cooperating parts, or analogous arrangements may be used alone both for the purpose of (topics of this patent may be obtained for arresting the creeping tendency of the rail, through the medium of the tie and for preventing a displacement of the tie itself.

Various changes in the specific forms shown and described may be made within the scope of the claims without departing from the spirit of my invention.

I claim: 7

1. A road bed comprising a flanged girder, a tie laid loosely thereon, a rail secured to said tie, a clamp connected with the flange of said girder, and a wedge engaging said tie and cooperating with said clamp to arrest a displacing movement of said tie relatively to said supporting means.

2. A road bed comprising a girder, a tie laid loosely thereon, a rail secured to said tie, antircreeping means engaging said tie and rail for checking a creeping movement of the latter, and similar means engaging said girder and tie and operating in opposition to said anti-creeping means for opposing a displacement of the tie induced by the creeping tendency of the rail.

A road bed comprising a flanged gird-er, a tie extending transversely thereto and loosely laid thereon, a rail secured upon said tie, anti-creeping means connected with said rail and cooperating with said tie for checking a creeping movement of said rail, a clamp detachably connected with the flange of said girder and a wedge engaging said tie and cooperating with said clamp to arrest a displacement of said tie under the influence of said anti-creeping means.

1. A road bed Omprising a flanged girder, a tie extending transversely thereto and loosely laid thereon, a rail secured upon said tie, a clamp detachably connected with the rail-base, a wedge engaging said tie and cotjperating with said clamp to arrest a creeping movement of said rail, a second clamp detachably connected with the flange of said girder, a second wedge engaging said tie and cooperating with said second clamp toarrest adispl'acement of said tie on said girder, said two wedges operating in opposition to each other.

In testimony whereof I have hereunto set my hand.
